ABRAHAM H. JOHN, OF KIRKSVILLE, MISSOURI, ASSIGNOR OF ONE-HALF TO SAMUEL M. PIOKLER, OF SAME PLACE.

DISTILLING APPARATUS.

I SPECIFICATION forming part of Letters Patent No. 265,323, dated October 3,1882,

Application filed J nne 27, 1882.

To all whom it may concern Beit known that I, ABRAHAM H. JOHN, of Kirksville, in the county of Adair and State of Missouri, have invented certain Improvements in Distilling Apparatus, of which the following is a specification.

My invention relates to the'distillation of spirituous liquors, essential oils, 850., and is mainly designed for domestic or general use,

[0 with small portable apparatus instead of the costly plan commonly employed.

The invention consists in the adaptation of the apparatus todomestic use and rendering the same conveniently portable; in the employment of a tin or tin-surfaced evaporator, and in a peculiar construction of the condenser.

The apparatus consists'of a boiler or evaporator adapted to be placed and used upon a common stove, a condenser, and a water tank or supply adapted to maintain a continuous and uniform flow of water through the waterchamber of the condenser.

In the accompanying drawings, Figure 1 represents a side elevation of my improved appa- '25 ratus mainly in section, and Fig. 2a plan view of the condenser.

A indicates a common cook-stove, and B an evaporator or boiler in which molasses or other saccharine matter previously fermented by the aid of yeast in the ordinary and well-known manner is placed. The evaporator may conveniently be a common wash-boiler; but the cover should be clamped down or made fast by clamping-screwsa,orequivalentdevices,to pre- 3 5 veuttheescape ofvaporotherwise than through the pipe 0, which communicates with the condenser D.

It is important that the evaporator or boiler (No model.)

pipes are carried downward within the drum or body of the condenser to about one-third or one-half its length, to deliver the vapor at or about the medial line of temperature of the surrounding water. By thus carrying the months 5 of pipe 0 below the top of the condenser the vapor is brought at once to the cooler portion of the condenser-surface, and the condensation is very rapid instead of remaining at the top of thecondenser,asitwouldotherwise be apttodo.

The condenser consists of a doublewalled cylinder or drum, 1), formed of two concentric pipes, b and c, the intervening space between which is closed at the ends by annular heads 61, forming a closed chamber or vessel, into which the vapor is conducted by the pipe 0, and from which the distillate is withdrawn through a pipe, 6, and cock f at the bottom. Pipes or tubes 9 extend through the closed annular chamber of the condenser from end to end and through the heads (I, said pipes being of a diameter somewhat less than the width of the annnlarspace or chamber of the condenser, and placed at distances apart corresponding substantially to their diameter. The corrugations of the pipes or walls b o are made concentric with the tubes g, or practically so. This construction al'lords a very extended surface for condensation of the vapor, which comes in contact with the corrugated interior faces of the pipes b c and the exterior surface of the tubes 9 in the form of a thin film or stratum. The condenserthus formed is immersed in water in atank, E, for which 1 preferably employ a common cask, as being readily obtainable and very suitable, the outlet-pipe e of the condenserpassingoutthroughitsside,asi ndicated, and being properly packed to prevent leakage around it, the condenser being raised somewhat above the bottom of the tank or cask E, to permit the water to pass beneath it.

To maintain a proper temperature of the water it is necessary to change the same constantly, and to do this to the best advantage I enploy a smaller tank, preferably cask or keg F, and place the same directly above the cask E, which serves as a support therefor. From the bottom of the tank or keg F a pipe or tube, h, passes downward centrally through the drum or body of condenser D to a point somewhat ICO below the bottom of the condenser, as shown in Fig. 1. The tanks or vessels being filled with water, that contained in tank F flows down through pipe 7!, and escaping at the lower end is discharged equally in all directions around the same, and rises to displace the warmer water, which overflows through a pipe or outlet, 17. In this way the water is caused to pass upward through the tubes 1 and in contact with the inner and outer walls of the condenser. The vapor in the chamber or interior ofthe coudenser D is thus exposed to a very extended cooling or condensing surface, and is rapidly and e'tticiently cooled, the quantity of water required being reduced to the minimum.

In practice I prefer to slightly dish the bottom of tank F to insure the perfect discharge of water therefrom.

The apparatus thus constructed is exceedingly simple, etticient, and easy of manipulation, and can be constructed, set up, and operated by persons having little or no previous experience in such matters. The parts required can be procured in any town or village, and the apparatus is therefore peculiarly suited for farm or domestic use.

It is obvious that mash may be distilled in this apparatus, as well as molasses, sirups, or other saccharine preparations.

The evaporator is provided with a thermometer and a safety-valve, as indicated.

Having thus described my invention, what I claim is-- 1. The herein-described portable distilling apparatus, consisting of evaporator B, pipe 0, condenser composed of tanks 15 F, pipes h i, and corrugated body I), having tubes 9 within the corrugations, all combined and operating as explained.

2. The herein-described condenser, consistingot'corrugatedhollow-walled cyliuderl.),havingopen-ended tubes 9 within the corrugations, tank E, surrounding cylinder 1), and tank F, mounted above tank E, and having dischargepipe h, extending downward centrally within the cylinder D, substantially as shown and de scribed.

3. In combination with the condenser consisting of cylinders or drums be, corrugated as shown, and tubes g, placed within said corrugations, water-tanks E and F, the latter being placed above the condenser and provided with a pipe, 71, extending centrally through the condenser to a point below the same, whereby the water is caused to pass upward through the tubes and in contact with the inner and outer walls of the drum.
